I know nothing about it other than that it exists and having briefly scanned 2 pages, here's a copy of one:
"Amazon FPS Pricing
There is no minimum fee and no start-up charges to use Amazon FPS. In addition, you can use the Amazon FPS Sandbox for free. Fees are assessed on a per-transaction basis and vary depending on the payment method used and the transaction amount:
1.5% + $0.01 for Amazon Payments balance transfers.
2.0% + $0.05 for bank account debits.
2.9% + $0.30 for credit card for transactions above $10 and 5%+$0.05 for credit card for transactions below $10.
Different fees apply for transaction amounts less than $0.05. Learn more about micro-transaction pricing and how you can qualify for volume discounts.
Note: This fee schedule is for payments by US customers only. For an additional charge of 1% of the transaction amount, non-US customers can make payments using credit cards (but not using Amazon Payments balance transfers or bank accounts at this time)."
